I personally don't see the point in having a master password that one cannot type correctly. But this extensions seems to be valid. The code does not contain anything harmful, just switches the type of the input field on toggle.
It's just an annoyance for the lack of option to display the password upon typing. It is good for you to identify the typo in case your password is very complicated.
What I only want is an option to display the Master Password, but not all password fields. So, one password rules all without a great compromise in security in combination with Secure Login.
Why are there several strange 1-star reviews at the bottom? Do they know a "cancel" button is always with the master password prompt? As clicking cancel will not have any negative effect on the password protection mechanism, unless the password is filled in, no one can access the password database.
Also, please update this for the Firefox 3.5, so more people can benefit from this addon.
Clean code... :) But I think the addon prepared by me solve the problem in a more user-friendly manner.... It has a cool small icon on the lower left corner.. I suggest you should improve your addon on that line...
Best of Luck!!! https://addons.mozilla.org/en-US/firefox/addon/10174/
...but this extension does not change anything to the CANCEL button!
The default behaviour should be, that every password is NO protection againt starting the application - but you should get no access to stored passwords (when cancelling the Master Password) or do not receive any mail (when cancelling mailbox password)...
